Thank you for viewing. I am selling this due to a change in specifications. This is a rare RC-ART HP damper that is not often available now. It was easy to use with its supple suspension. The O-rings were recently replaced with Reve D ones. Retainers are not included, so please prepare them yourself. Spare parts other than O-rings are included. Everything in the pictures is included. Please consider purchasing only if you understand that this is a used item.
